We are trying to identify the best way to to perform a lightshed analysis in our community. Typically, our streetlights stand about 300' apart. The obvious step seems to be creating a buffer around each streetlight and seeing which areas aren't covered. However, buildings are going to cause obstructions, so a streetlight on one street might appear to have a certain lightshed, but then there might be a building blocking it on one side so the light from that streetlight isn't going to hit areas of a perpendicular street.
If anyone has any thoughts related to this, I'd love to hear them! Thanks!
